The NYC mayor will also host a fundraiser for former DreamWorks executive Greuel at a Park Avenue club on May 20th, according to sources. Audrey Gelman, Lena Dunham’s friend and Girlsmuse, is expected to co-host the event, along with Alliance Hollywood founder Nomiki Konst.

With the June 3rd primary election less than a month away, former LA mayoral candidate Greuel and seven other candidates are locked in a battle for endorsements and campaign funds. The hopefuls include State Senator Ted Lieu, author and inspirational speaker Marianne Williamson, Venice defense attorney David Kanuth, radio host Matt Miller and lawyers Elan Carr, Barbara Mulvaney and Tom Fox.

The top two winners in next month’s primary battle will square off in the November election.
